FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 410,235, datedSeptember 3, 1889.

Application led January 30, 1889. Serial No. 298,152. (No model.)

T0 all whom, it may con/cern:

Be it known that we, DANIEL A. DRAPER and ALFRED TONKS, citizens of theUnited States of America, residing, respectively, at East Cambridge andMalden, county of Middlesex, and State of Massachusetts, have jointlyinvented certain new and useful Improvements in Fire-Arms, of which t-hefollowing is a full, clear, Aand exact description.

. This improvement in iire-a-rms is more especially designed forcombination with a walking cane or stick; and it particularly relates toa lire-arm of the class represented by Reissued Letters Patent of theUnited States, dated March 20, 1888, No. 10,910. 'Ihe mechanism of thisgun, as in said patent, consists, in substance, of a gun-barrel,(breech-loading,) a breech-block hinged on the barrel to be openedtherefrom and closed thereon, a firing-pin extending and slidinglengthwise through the breech-block and adapted to be set for firing thegun and to be impelled against the cartridge with which the gun ischarged by the action of a spring conined end to end thereon and in thebreech-block, a trigger to hold the firing-pin when set and to releaseit to action, and a sleeve preferably detachably attachable to and tosurround breechblock and barrel at its breech end and adapted to berotated on and to be moved lengthwise of breech-block and barrel, so asthereby to be placed to lap thejoint of breech-block and barrel, toallow the breech end of barrel to be opened and closed and thebreech-block and., barrel to be placed at an angle to each other byswinging the breech-block on the barrel, to withdraw the firing-pinagainst its spring, and to permit trigger to be operated to free thefiring-pin for discharging the gun.

This invention as to the mechanism described in substance consists,first, of a rod which is in extension of the firing-pin beyond the rearof the breech-block and has a lateral projecting shoulder, incombination with the sleeve, which is arranged to slide lengthwise ofsaid rod-extension, and preferably over the breech-block and barrel, andhas a cross-partition in position as the sleeve is drawn backwardlengthwise of said eX- tension to abut against the shoulder thereof,

and thereby withdraw the firing-pin against its spring, setting it for adischarge of the gun; second, of a rod of polygonal shape incross-section, which is in extension of the firing-pin beyond the rearof the breech-block and has a lateral projecting shoulder and adepression between its said shoulder and the firing-pin, in combinationwith the sleeve, which is arranged to slide lengthwise of said extensionand has a cross-partition having a polygonal-shaped opening to iit saidpolygonal-shaped extension and to receive its lateral projectingshoulder, and also that the partition of the sleeve and depression ofsaid extension registered or in line with each other. The sleeve can berotated about the ex.- tension, and thereby the opening thereofregistered with the shoulder of the extension for the sleeve to be movedlengthwise of and detached from the extension, or said opening placedout of said register for its partition on then drawing the sleevebackward along` the extension to abut against the shoulder thereof, andthereby withdraw the ring-pin against its spring to set it for adischarge of the gun.

In the drawings forming part of this specification, Figure 1 is a sideview ofthe barrel, breech-block, and rod in extension of firingpin, andshowing the breech-block closed on the barrel, the firing-pin in itsnormal position, and a central longitudinal section of the sleevesurrounding both barrel and breechblock and-in a position, if then drawnlengthwise backward over the barrel and breechblock, to withdraw theIiring-pin against its spring, and thus to set it preparatory to firingthe gun by operating the trigger'. Fig. 2 is a central longitudinalsection, line 2 2, Fig. 1. Fig. 3 is an end view of the breech-blockwith the barrel detached. Figs. 4, 5, and 6 are cross-sections, lines 44, 5 5, and 6 6, respectively, Fig. 2l

In the drawings, A is the barrel, breechloading.

B is the breech piece or block, pivoted or hinged to breech end ofbarrel, so as to be registered with to close or to be placed at an angleto open the barrel.

C is the firing-pin.

IOC)

E is a spiral spring for forcing the firingpin C forward to dischargethe cartridge with which the barrel is charged.l

D is the catch or trigger to hold the firingpin retracted preparatory todischarging the gun, and F is a sleeve surrounding barrel andbreech-block and arranged to be rotated on and to be moved lengthwise ofbarrel and breech-block, all as described in said Reis sued LettersPatent, except as hereinafter particularly explained.

G 'is a rod in extension of the firing-pin C, and projecting from therear end of the shell or casing J in ertensionA of the breech-block.This shell contains a coiled spring E, confined end to end on firing-pinC, which on withdrawing the firing-pin is compressed and acts to forcethe firing-pin forward to discharge the cartridge with which the gun isloaded, as described in said patent. The rod-extension G of firing-pinGis of polygonal shape in cross-section, particularly shown assquaresided, and passes loosely through a corresponding-shaped holeb ofa fixed cross-partition H of the sleeve F, and thus the sleeve is heldagainst turning about, but is free, all otherwise being suitable, to bemoved lengthwise of said rod G.

fis a fixed radial pin at the outer end portion of the extension G ofthe firing-pin.

a is a depression around the firing-pin extension G and between it andthe firing-pin. This depression a, as particularly shown and incross-section, is round and of a length equal, at least, to thethickness of the sleeve-partition H.

With the partition H registered with the depression a. of rod G, or, inother words, with the partition and said depression in the sametransverse plane, the sleeve can then be turned about the rod G.

g is a radial or diametrical slot of the sleeve-partition H, and it isof suitable dimensions to receive the radial pin f of the rod G when itis registered, or, in other Words, it is in the same direction as thatof the pin f.

Z is an aperture at one side and intermediate of the length of thesleeve F, and of suitable size when registered with or opposite to thefinger-piece of the trigger D to expose it for being pressed upon by thefinger to release the trigger from the firing-pin, and thereby torelease the firing-pin to the action of its spring E for the dischargeof the gun.

The barrel and breech-block in line with each other, the sleeve F, Figs.l and 2, in its normal position surrounds the barrel at its breech end,the breech-block, the shell E, in extension of the breech-block, and therod-extension G of iiring-pin, and its partition H is engaged with therod-extension, and the radial slot of said partition is out of line withthe pin f of said extension, and its aperture l is forward of thetrigger. Now, drawing the sleeve over the barrel and breech-block, thehinge of .barrel and breech-block is first eX- posed, so that thebreech' of the barrel can be sleeve is returned to its normal position,Figs.

l and 2, to bc again manipulated, as before.

The sleeve F, in the position described and shown, Figs. l and 2,plainly, is held on the rod-extension G of "firing-pin C and movedlengthwise of said rod G. The barrel and breech-block are exposed to beopened and closed or otherwise adjusted as to each other, the firing-pinset, and the discharge of the gun secured, all as has been explained.

To remove the sleeve from the rod-eXtension G of firing-pin C, firstdraw the sleeve backward sufficiently to register its partition H withthe depression a of said rod G, and having then turned the sleeveone-quarter round continue to draw it back sufficiently to pass itspartition H by its slot g over the pin f of the rod G, when the sleeveis set free. A quarter-turn of the sleeve F, as explained, places theslot g of its partition H in a corresponding-radial direction, or, inother Words, registers it with the pin f of the rod-extension G of'firing-pin C.

To place the sleeve F on the rod-extension G of firing-pin C, iirstregister the slot g of its partition H with the pin f of said rod G, andthen move the sleeve forward, and, having registered its partition withthe depression of said rod G, turn the sleeve one-quarter round, whichplaces the slot g ot its partition out of register, and then move itforward into the position shown in Figs. 1 and 2, and the attachment ofsleeve F to rod G is completed.

As guides for registering the slot g of sleevepartition H, as explained,the barrel A has two parallel lines at two points p a of its perimeter,Figs. l and 3, running lengthwise of it,

and the sleeve has one line at the point m of its perimeter, Fig. 4,running lengthwise of it and from its end which is toward the barrel A.The points p n are quartering as to the circumference of the barrel, andthe point/p is coincident with the pin f of the rod-extension offiring-pin. To draw the sleeve backward to set the firing-pin, asdescribed, the

line at the point fm of the sleeve F must co- IOC IIO

at right angles to the line through the points p n of the barrel, andwith which the end of the sleeve which is toward the barrel is made tocoincide before turning the sleeve.

fr isa spring coiled about the rod-extension G of tiring-pin C, agdconfined, end to end, between the rear end of shell J of breech-block Band a washer t on said rod G, and resting against a cross-pin d of saidrod, Figs. l and 2. This spring r acts as a butter on thesleevepartition when the sleeve is moved forward to position, Figs. land 2, and while it is desirable to use it, yet it is in no wayessential or requisite otherwise than as just stated.

Having thus described our invention, what we claim, and desire to secureby Let-ters Patent, is-

1. The combination, with a barrel A, a breech-block B to open and closethe barrel, and having a firing-pin C, a spring E, to actuate saidring-pin, and a trigger D, all substantially as described, of anextension G of the tiring-pin, having a projection f, and a sleeve F,having a partition H, to slide on and to abut against the projection fof said eX- tension, substantially as described, for the purposespecified.

2. The combination, with a barrel A, a breech-block B to open and closethe barrel, and having a firing-pin C, a spring E, to actuate saidiiring-pin, and a trigger D, all substantially as described, of anextension G of the firing-pin, and which is of polygonal shape incross-section, and has a projection f and a depression a between saidprojection f and the iiring-pin, and of a sleeve F, having a partitionH, with a hole b to iit said eXtension and its projection f, and toslide and rotate on said extension and to abut against and pass over itsprojection f, substantially as described, for the purposes specified.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
